[Profiling workflow for dotnet/runtime repository](https://github.com/dotnet/performance/blob/master/docs/profiling-workflow-dotnet-runtime.md)
[Benchmarking workflow for dotnet/runtime repository](https://github.com/dotnet/performance/blob/master/docs/benchmarking-workflow-dotnet-runtime.md)

Start with the linked benchmark source in dotnet/performance at src/benchmarks/micro/libraries/System.Runtime.Numerics/Perf.BigInteger.cs#L146-L149, then run the provided benchmarks_ci.py command with the System.Numerics.Tests.Perf_BigInteger filter. Compare the reported baseline and test results and review the linked test history and report; done requires a clear, reproducible triage of the recorded performance improvement.
